NAME

       XSetPointerMapping, XGetPointerMapping - manipulate pointer settings

SYNTAX

       int XSetPointerMapping(Display *display, unsigned char map[], int nmap);

       int XGetPointerMapping(Display *display, unsigned char map_return[], int nmap);

ARGUMENTS

       display   Specifies the connection to the X server.

       map       Specifies the mapping list.

       map_return
                 Returns the mapping list.

       nmap      Specifies the number of items in the mapping list.

DESCRIPTION

       The XSetPointerMapping function sets the mapping of the pointer.  If it succeeds, the X
       server generates a MappingNotify event, and XSetPointerMapping returns MappingSuccess.
       Element map[i] defines the logical button number for the physical button i+1.  The length
       of the list must be the same as XGetPointerMapping would return, or a BadValue error
       results.  A zero element disables a button, and elements are not restricted in value by
       the number of physical buttons.  However, no two elements can have the same nonzero value,
       or a BadValue error results.  If any of the buttons to be altered are logically in the
       down state, XSetPointerMapping returns MappingBusy, and the mapping is not changed.

       XSetPointerMapping can generate a BadValue error.

       The XGetPointerMapping function returns the current mapping of the pointer.  Pointer
       buttons are numbered starting from one.  XGetPointerMapping returns the number of physical
       buttons actually on the pointer.  The nominal mapping for a pointer is map[i]=i+1.  The
       nmap argument specifies the length of the array where the pointer mapping is returned, and
       only the first nmap elements are returned in map_return.

DIAGNOSTICS

       BadValue  Some numeric value falls outside the range of values accepted by the request.
                 Unless a specific range is specified for an argument, the full range defined by
                 the argument's type is accepted.  Any argument defined as a set of alternatives
                 can generate this error.
